Definitions
- the present invention relates to a polyunsaturated fatty acid-containing fat. More specifically, the present invention relates to a polyunsaturated fatty acid-containing fat and oil that achieves improved oxidation stability, which is required for a food containing a polyunsaturated fatty acid-containing fat and oil, a food containing the same, and a method for producing the same.
- n-3 fatty acids which are essential fatty acids, for health is widely known, and the demand is increasing.
- n-3 fatty acids include ⁇ -linolenic acid (C18: 3), docosahexaenoic acid (DHA; C22: 6)), eicosapentaenoic acid (EPA; C20: 5), docosapentaenoic acid (DPA; C22: 5) Etc.
- n-3 fatty acids contain many double bonds in the constituent fatty acids
- the fats and oils containing the n-3 fatty acids are not stable and have a rapid deterioration in flavor. Precautions such as storage at low temperature or light shielding are necessary, and as a result, applications as general edible oils are limited, and fats and oils that contain a large amount of n-3 fatty acids and have high stability are desired. ing.
- Cited Documents 1 to 8 are disclosed as methods for making an emulsion
- Cited Documents 9 to 10 are disclosed as methods for powdering or encapsulating. When an emulsion is used, the use is limited because it becomes turbid in a translucent state or contains water.
- Cited Document 11 discloses a method in which an oil containing 30% or more of DHA having poor oxidation stability and other oil are mixed and used as an edible oil composition for cooking by heating.
- the amount of DHA blended is as small as 0.01 to 0.5%, and it is far from ingesting an amount effective for health.
- Refined polyunsaturated fatty acid-containing fats and oils are free from odors and peroxides, but when oxidation occurs, the reaction proceeds in a chain, and it is known that degradation odors and peroxides are rapidly generated. Yes.
- polyunsaturated fatty acid-containing oils and fats in a factory, it is necessary to seal nitrogen gas and then seal the cans. Use is naturally limited. Many attempts have been made to stabilize polyunsaturated fatty acid-containing fats and oils by adding various antioxidants or mixtures thereof, but they have not achieved sufficient results so far, and demand from the market On the other hand, development of foods containing polyunsaturated fatty acid-containing fats and oils cannot be said to be sufficiently advanced.
- an antioxidant is generally added to improve the oxidative stability of edible fats and oils.
- a fat-soluble antioxidant tocopherol, ascorbyl palmitate, and the like are being studied.
- Cited Document 2 as a method for adding tocopherol / ascorbic acid and tea extract, Cited Document 12, adding ascorbic acid or a salt thereof and another organic acid or a salt thereof.
- Cited Document 13 is disclosed as a method, it is not satisfactory as a method for improving the oxidative stability of polyunsaturated fatty acid-containing fats and oils, and a more excellent antioxidant method is desired.
- Patent Document 13 100 parts by weight of an aqueous solution containing one or more water-soluble antioxidant active substances is emulsified with 1 to 500 parts by weight of one or more lipophilic emulsifiers, if necessary, together with a synergist.
- a water-in-oil type lipophilic antioxidant is disclosed.
- Patent Document 14 a water-soluble compound excluding catechins and an emulsifier having an HLB of 6 to 14 are dissolved in water or alcohol, and a polyglycerin condensed ricinoleic acid ester is added to the resulting solution to obtain a polyglycerin condensed ricinoleic acid ester.
- a water-soluble compound oil-solubilized preparation that is soluble in fats and oils, obtained by preparing a water-in-water emulsion, adding 0.5 to 30 parts by weight of enzyme-decomposed lecithin to this emulsion, and mixing thoroughly. ing.
- an antioxidant that is hardly soluble in fats and oils such as ascorbic acid, erythorbic acid, kojic acid, gallic acid, malic acid and the like is dissolved in a lower alkyl alcohol such as ethanol, and then an organic acid monoglyceride such as citric acid monoglyceride.
- an antioxidant composition having good solubility in fats and oils by dissolving the mixed solution in polyglycerin condensed ricinoleic acid ester is disclosed.
- Patent Document 16 discloses a method for producing a catechin-dispersed oil or fat characterized by adding hexane-soluble components derived from green tea and catechin to oil and fat, heating to 70 to 130 ° C., and grinding.
- Cited Document 17 As a process for improving the oxidative stability of polyunsaturated fatty acid-containing fats and oils, in Cited Document 17, fish oil is treated with silica gel, vacuum steam deodorization is performed in the presence of rosemary and sage extract, palmitic acid ascorbic acid ester and mixed A method characterized by adding tocopherol is disclosed. In this way, the problem of aroma peculiar to rosemary and sage is excluded, and an oil and fat with high oxidation stability is proposed.

香気成分の分析法; 3gの油脂において、60℃・15分保温し、Divinylbenzene/Polydimethylsiloxane/Carboxenのファイバーに吸着(60℃・15分)させた後、240℃で香気成分を脱着させ、260℃で20分焼き出し、GC-TOFMSにて香気成分を分析した。GC部のカラムはStabil-WAX(長さ30m・内径0.32mm・液相膜厚0.5μm)を使用した。
所定の香気気成分(α);
2-Heptenal、2,4-Nonadienal、2,4-Heptadienal、3,5-Octadien-2-one、2-Butenal、3,4-Pentadienal, 2,2-dimethyl、1-Penten-3-one、2,4-Hexadienal、2(5H)-Furanone, 5-ethyl、
所定の香気気成分(β);
Phenol、Toluene―
・実施例B1~B13は、調整直後の風味が良好で、A/Sの値は何れも0.8以上であり大豆油と同等に使用可能な油脂であった。
・比較例B4は、白濁が強い上に酸化安定性も低く、使用不可であった。
・比較例B5は、実施例B1、B2と同等な水溶性茶ポリフェノールを添加しているが、水溶性茶ポリフェノールの分散性が悪く、水溶性茶ポリフェノール添加量に応じた十分な効果が得られていない。
・比較例B6はA/Sが0.8以上あったが、調製直後に乳化剤特有の臭気があり、食用として使用不可であった。
・比較例B8のA/Sは0.8であったが、茶ポリフェノール製剤特融の刺激味や臭気が調整直後から存在し、使用不可であった。
・比較例B11は、二重結合が5つ以上の脂肪酸の量に対して、水溶性茶ポリフェノール含量が十分でなく、A/Sは0.8未満の0.41であった。
・60℃3日後のGC-TOFMS分析によるα/β値が7以下であった実施例B1~実施例B12の高度多価不飽和脂肪酸含有油脂は、60℃3日後の風味評価も良好な結果が得られた。
・実施例B4、実施例B6、実施例B13は調整直後の風味が実施例B1よりも若干劣ったが、GC-TOFMS分析によるα/β値が7以下で良好で、60℃3日後の風味評価も良好であった。
・比較例B4は、白濁が強かったことから使用は困難と考え、保存テストは実施しなかった。
・比較例B5は、実施例B1、B2と同等な水溶性茶ポリフェノールを添加しているが、水溶性茶ポリフェノールの分散性が悪く、水溶性茶ポリフェノール添加量に応じた効果が得られていないので、保存テストは実施しなかった。
・比較例B6~比較例B8は、初期の風味評価が著しく悪く、保存テストは実施しなかった。
・実施例B11は、CDM安定性時間は実施例B2と同等であるが、60℃3日後の風味評価およびGC-TOFMSのα/β値は実施例B2よりも好ましい結果が得られた。
・60℃3日後のGC-TOGMS分析によるα/β値が7.89であった、比較例B11の60℃3日後の風味評価結果は、不合格であった。
